Does Your Galaxy S4 Have a Dead Pixel?

Hi. I have discovered two dead pixels on my screen: One in the middle and the other closer to an edge.
I am going to return the phone, but, before ordering a replacement, I would like to know if it's a common occurrence. Possibly, batch related?
Best way to check for a defective pixel is to:
Increase brightness to the max (uncheck auto brightness)
Download and install a free app called Dead Pixel Test by UJACHA from Google Play: https://play.google.com/store/apps/...GwsMSwxLDIxMiwibmV0LnVqYWNoYS5kZWFkcGl4ZWwiXQ..
Cycle through the colors and inspect the screen.
Warning: Dead pixels cannot be unseen :laugh:

didn't find any dead pixels. But I do have the smearing issue

None here! Love this phone

No one here. :good:

Nope, good to go.

Thanks everybody. looks like I am safe to order a replacement as it's likely not first batch related.

I have dead pixels
Hello,
I have the same problem. I have 6 (YES 6!!) pixel dead on my Samsung Galaxy S4
I buy it the launch day.
I don't know if they are dead since day 1. They are soooooo small. At first, i did not see them. But after I see one, i used a grey background color and start to find few of them. I used a program to restore dead pixel, it basicly flash all colors for 30 min, without success
This phone is really the best phone I ever had and pixels are so small it's hard to see it, but i'm a little bit dissapointed.
To see if you have dead pixels, I strongly recommand to use the grey background, then wait on night or before you go sleep when is dark in your room, you will find them only at this moment. On daylight it's almost impossible to see, unless you know exactly were they are.

Dead Trigger 2 is compatible!

Hello Nvidia Users,
its more than a week since Dead Trigger 2 has been launched. And its compatible with the Nvidia Shield and graphically enhanced for Tegra 4. Plays great!
Link to Google Play
https://play.google.com/store/apps/details?id=com.madfingergames.deadtrigger2&hl=de
I wondered because no one posted this here?!

Its a great looking game. I talked to one of the devs and he said at some later date a big update will be released which will include online play. Does that mean co-op missions? I don't know but it sounds good.

I've found a problem with dead trigger 2 on Nvidia shield. If you run at the recommended ultra-high graphics setting, there will be certain areas/maps where the frame rate will drop significantly when looking in certain directions. The bigger problem is that either the game or the controller interface is also affected by the lag. So while you play with lower frame rate, the game time remains unchanged. However, turn/rotate speed is affected by frame rate! So while getting low fps as you turn around, for example, you will end up turning only 1/3rd the amount you wanted to turn.
It's very frustrating and I had to lower graphics settings to resolve the issue. But it's weird because you'd think the tetra 4 with the shields active cooling system could handle this game at 720p, when the iPad 4 can handle it at nearly 3x the pixel count.

I recently noticed the same slowness and I gotta say its really disappointing to see since the shield is supposed to be so powerful. I might have to email the devs about this.

[Q] Dead Pixels

I am using a Samsung Galaxy Note II phone. I have dead pixels in my screen from an accident. I've tried putting it in the freezer 3 times but no results. Can anyone give me step by step instructions to get results?
Thanks

You tried any of the dead pixel apps on play store??

By the way, I'm no expert but that doesn't look like normal stuck pixels to me. Looks like you have damaged your hardware from this "accident".

Try this cod *#0*# this is LCD Test and then press on the red, green and blue buttons and you will see if you have dead pixels

Daydream VR Drift

Just got my Daydream View and tried it out with my Pixel XL, all seems good except I get extreme drift to the right hand side, you can hold down home button for a few seconds to recentre, but I am having to do this about once every 30 seconds. Is there a way of calibrating this, or does it indicate a fault with my phone?

contact google.

I did, they got me to reset apps download manager and play store, to reset the auto date/time, but it did not make a difference just trying to work out if this is normal, or my phone is slightly off?

Might be a daydream software issue. I know my note 7 always had drift using cardboard, but worked fine on gearvr.

Ha, mine drifts to the left.
The battery in my controller finally just died on me today, It seems to have gotten worse the lower the battery got.
I'm hoping it will drift less with a full charge.

Zenfone 2 Zoom touchscreen dropping swipes

I've had a Zenfone 2 Zoom for about year and used it lightly only for testing. Recently it seems applications are getting worse with acknowledging rapid strokes. It used to be with Minion Rush I could play the game and only very fast strokes would get dropped (the reason described below), and now it's practically unplayable. The issue also affects two similar games, Paddington and Subway Surfers.
ASUS support site doesn't seem to have any specific recommendations other than adjusting Glove Mode. It's been with the factory ROMs since day one and currently has WW_4.21.40.209_20161216. Check for updates doesn't show any new ones.
I've had Developer Mode on since I first observed the symptoms, and I can see the digitizer has issues with fast strokes; usually they end up around 10 pixels long, clearly showing the digitizer isn't processing the correct request. The rest of the strokes are showing up, some are double-banded and some longer than expected, which also raises concern, but the rest of the UI and other programs all work fine. So far, only the rapid strokes of certain game genres seem to have issues. And with these games, I can see the strokes on screen, but the game isn't picking it up.
Will loading a custom 7 build fix this issue or should I toss it due to being bad hardware?
